I'm not familiar with this error. Have you opened a support ticket?
What version is this? Are you using the correct installer? Is iptables running? When you run "ps -ef | grep rscd" is the process running successfully or is it defunct?
It will be better if you provide the complete job run log
BTW you can also do a couple of checks -
1. sshd is running on target machine.
2. <NSH_INSTALL_DIRECTORY>/bin/rscd is not present on target machine. you can run 'cat /usr/lib/rsc/HOME' to find the install directory
